第二節(jié)  完形填空

The art of living is to know when to hold fast and when to let go.When know that this is(36),but all too often we recognize this truth(37)in our backward glance when we remember what it was and then suddenly(38)that is no more.

      Hold fast to life,but not so fast,or you cannot(49).This is the second side of life's(50),the opposite pole of its paradox(悖論)：we  must (51)our losses,and learn how to let go.

第三部分閱讀理解

A

One day,an expert in time management was speaking to a group of students and ,to drive home a point,used an illustration those students will never forget.

Standing before the group of overachievers(成績超過預料的學生）,he said,"Ok,time for a quiz."He pulled out out a one-gallon,wide -mouth jar and set it on the table in front of him.He also produced about a dozen fist-sized rorocks and carefully placed them,one at a time,into the jar.When no more rocks would fit inside,he asked,"Is this jar full?"

Everyone in the class yelled,"Yes"The expert reached under the table and pulled out a bucket of gravel.He dumped some gravel in and shook the jar,causing pieces of gravel to work themselves down into the spaces between the big rocks.He then asked again,"Is this jar full?"

"Probably not."one of them answered."Good."He replied.He reached under the table and brought out a bucket of sand.He started dumping the sand in the jar and it went into all of the spaces left between the rocks and the gravel.Onece more he asked the question,"Is this jar full？”

“No!"the class shouted."Good."He replied.He grabbed a pitcher of water and began to pour it in until the jar was filled to the brim.Then he looked at the class and asked,"What is the point of this illustration?"One eager student raised his hand and said,’“No matter how full your schedule is,if you try really hard you can always fit some more things in it!"

"_______,"the expert replied.“The truth this illustrtion teaches us if you don't put the big rocks in first ,you'll never get them in at all.What are the "big rocks"in your life?Time with your loved ones,your education,your dreams,a worthy cause,or teaching others?Remember to put these big rocks in first or you'llnever get them in at all."

For many students in Beijing,Mr.Obama symbolizes all that is possible in the United States.He's a popular winner here,seen as a self-made man who has made it to the top.

"I think he is very charming,and a president who can create a new era(時代）,"said ZhangWei,a university student."I like him very much and most of my friends do too."

Ni Weibo,another university student,agrees."Sino-U.S. Relations still need more cooperation,"she said."I think he will help take it to a new era."

China's President Hu Jintao congratulated Mr. Obama within hours of his victory,saying he hoped bilateral ties could be made stronger.

Political analysts(分析家）here say China will be looking for the incoming president to avoid contentious issues such as Taiwan's independence,human rights and Tibet.

Instead,they say Beijing would like Mr Obama to focus on solving the global economic crisis(危機),and to help China's slowing economy by opening up U.S. Markets.

But trade relations might be a sticking point,says Renmin University's Professor of International Studies,Shi Yinhong.

He warns,"There is a possibility that President Obama will take some protectionist measures which China will not  accept,then trade disputes could develop to a degree that we have not seen ever before."

Despite making the headlines,Mr.Obama faces some tough challenges in managing the U.S. Relationship with China.

China is now a stronger and more confident country than the China his predecessors(前任)dealt with.And in this time of economic uncertainty,analysts say it's a country with wich Mr.Obama will want to maintain a good relationship.

60Many students in Beijing  expect that Mr.Obama  can________.

A.made everything possible  B.further strengthen Sino-U.S.relations

C.become a self-made man  D.try to help China into a new era

61According to some analysts,which of the following is what China would like Mr.Obama to do?

A.Facing some tough challenges  B.Taking some protectionist measures

C.Making Sino-U.S.bilateral ties stronger 

D.Opening up markets to speed China's economy

62The underlined word "dispute"means"______"

A.serious disagreemen  B.severe measures

C.tough crisis  D.confusing issues

63As mentioned in the text,Mr. Obama will want to maintain a good relationship with China because________.

A.China is now a stronger and more confident country

B.he has tough challenges in managing the relationship with China

C.he wants to avoid issues like Taiwan's independence,human rights and Tibet

D.Mr.Hu Jintao congratulated Mr.Obama within hours of his victory

It used to be that shopping was a fairly simple activity---you went to the supermarket,picked up what you need,paid for it and left.But in recent years it's become a lot more complicated.Supermakets in the UK now sell much more than food :you can get your insurance there ,pay bills and a variety of other services.In many ways they've become a one-stop shop for lots of life's daily chores.

You can also get "rewards"----join up and get a "loyalty card"and every time you shop you'll get points and discounts.And just when you thought supermakets couldn't offer anything else,they turned into mini-banks,offering you cash when you shop .Go into any UK supermarket,pay for your shopping,and you're more than likely to be asked if you want "any cashback with that?”

This is only offered if you pay by debit card(簽證卡）.Effectively,if you buy ζ30 worth of shopping,you can pay ζ50 with your debit card and the supermarket will give you your shopping plus,ζ20 in cash from the till(收款機）。

Originally introduced by the supermaket gaint Tesco,it eases busy shoppers' lives by cutting out an extra visit to the bank.Of curse, they didn't just introduce this for the customer's benefit---shops also benifit by having less cash in-house,and by paying less in fess for taking this cash to their local bank.

In recent years the phrase "cashback!"has also  been observed as an exclamation of joy or satisfaction,as in:"It's three drinks for the price of two in the pub tonight.Cashback!"

64Supermakets in the UK now are different from what it used be because_______

A.they will ask shoppers to pay only by cashback

B.they don't sell food and other daily necessitites

C.they have made shopping much more complicated

D.they provide a veriety of other services besides shopping

65.The cash you get when you shop in supermakets comes from the______.

A.points and discounts  B.built-in mini-banks

C.supermaket giant Tesco  D.extra visits to the bank

66Who will benefit from"Cashback!"?

A.Only busy shoppers  B.Only supermakets

C.The local banks  D.Both shoppers and shops

67What may be the best title for the text?

A.UK Supermarkets  B.Cashback!  C.One-stop Shops  D.The Best Services

     The intelligence of the dog is among the highest of all the animals,maybe higher than we give him credit for.Although his brain is only half as large as ours,he is certainly the most intelligent of domestic animals.

A scientist in Brazil has proven dogs can count.He used a technique which also proved that 5 month old infants can count:

"He placed treats in a bowl,hid it with a screen and let the animals watch as he removed or added some.The dogs studied the contents longer when the screen was taken away if a trick had been played leaving more or less treats than expected .He tasted 11 mongrels(雜種狗）and found they paid little attention when one plus one resulted in two treats.But they looked more closely when one plus one left three."

Memory is an important component of intelligence.The dog's memory for scents is extraordinary.His visual memory is only fair,but his memory for sounds is very good,since he can remember and identify familiar voices even after an absence of many years .While he builds up a large store of identifiable sounds without the slightest effort,remembering different words requires more concentration.

The dog's capacity for learning is more a matter of memory than of true understanding.He will remember the sequence of cause and effect in his actions,but he is unable to draw broad conclusions from his experience.The greater the variety of experiences and contact with others they have,the quicher they learn,and the more they retain.

Dogs are bound by nature to remain intellectually inferior to (劣于）man,but we owe them a chance todevelop their native intelligence by training,teaching,and working with them as much and as often as we can.

72This text focuses on dog's________

A.appearances and behavious  B.intelligence and memory

C.breeds and reactions  D.emotions and attitudes

73What does the experiment by the brazilian scientist show?

A.Dogs remain intellectually inferior to man

B.Dogs' brain is only half as large as human beings'

C.Dogs know the numbers if their attemtion is drawn

D.Dogs have the same intelligence as 5-month-old infants

74How does the dog recognize the owner after he has been away for quite a long time?

A.It has memory for scents and voice

B.It has true understanding of its owner

C.It has extraordinary visual memory

D.It often misses its owner and remembers him

75This text is most probably______

A.a book review  B.a travel journal  C.a research report  D.an animal test
